SURVEYING THE AGENTS OF GALAXY EVOLUTION IN THE TIDALLY STRIPPED, LOW METALLICITY SMALL MAGELLANIC CLOUD (SAGE-SMC). I. OVERVIEW [PDF]

, 2011
The Small Magellanic Cloud (SMC) provides a unique laboratory for the study of the lifecycle of dust given its low metallicity (~1/5 solar) and relative proximity (~60 kpc).

Evolution of the Small Magellanic Cloud [PDF]

, 2008
Based on the results of N-body simulations on the last 2.5 Gyr evolution of the Large and Small Magellanic Clouds (LMC and SMC, respectively) interacting with the Galaxy, we firstly show when and where the leading arms (LAs) of the Magellanic stream (MS)

Oxygen Isotopes Reveal Low-mass Star Dominance in the Small Magellanic Cloud [PDF]

The Astrophysical Journal
Oxygen isotope abundances and their ratios are fingerprints of stellar evolution, and therefore provide a powerful tool in tracing the enrichment history of galaxies.

Discovery of the Magellanic Stellar Stream Out to 100 kpc

The Astrophysical Journal, 2023
The Magellanic Stream (MS)—an enormous ribbon of gas spanning 140° of the southern sky trailing the Magellanic Clouds—has been exquisitely mapped in the five decades since its discovery.

Optical spectra of radio planetary nebulae in the large Magellanic Cloud [PDF]

Serbian Astronomical Journal, 2008
We present 11 spectra from 12 candidate radio sources co-identified with known planetary nebulae (PNe) in the Large Magellanic Cloud (LMC). Originally found in Australia Telescope Compact Array (ATCA) LMC surveys at 1.4, 4.8 and 8.64 GHz and confirmed by

Magellanic Clouds Cepheids: Thorium Abundances [PDF]

Journal of Astronomy and Space Sciences, 2018
The analysis of the high-resolution spectra of 31 Magellanic Clouds Cepheid variables enabled the identification of thorium lines. The abundances of thorium were found with spectrum synthesis method. The calculated thorium abundances exhibit correlations

An Unbiased CO Survey Toward the Northern Region of the Small Magellanic Cloud with the Atacama Compact Array. II. CO Cloud Catalog

The Astrophysical Journal, 2023
The nature of molecular clouds and their statistical behavior in subsolar metallicity environments are not fully explored yet. We analyzed data from an unbiased CO ( J = 2–1) survey at the spatial resolution of ∼2 pc in the northern region of the Small ...
